In a broad speech marking his first 100 days in office, Mayor Bill de Blasio reaffirmed his commitment to rebuilding a progressive city in the months and years ahead.

"We judge success on results -- on making a difference in the lives of real people in every neighborhood," de Blasio said in Manhattan on Thursday.

The mayor touted accomplishments during the address in Cooper Union's Great Hall, where Presidents Barrack Obama and Abraham Lincoln have spoken in the past. In re-outlining his administration's agenda, de Blasio quoted Lincoln, Plato and "The Honeymooners."

"If Ralph Kramden were standing here, he would say, at this moment, 'how sweet it is,'" de Blasio said.

Universal prekindergarten, the settlement of a stop-and-frisk lawsuit and the overall management of the city were among topics discussed during the speech, which was briefly interrupted for a campaign-style video where New Yorkers explained how the new administration's efforts have impacted their lives.

While de Blasio provided no new specific proposals or plans going forward, the speech served an opportunity for the mayor to galvanize supporters.

"We have so much more to do, but we know from what we've accomplished already that it can and will be done," he said at the end of the address.

Comptroller Scott Stringer said afterword that he believed de Blasio felt the need to remind New Yorkers the direction he wants the city to go. Still, Stringer said he was eager to hear more details about de Blasio's plans, particularly with regards to around 150 outstanding labor contracts.
